It is standard to use the notation f (xi) to represent the value of the function f (x) when x = xi.For example, if f (x) = x2 3, then f (1) = (1)2 3 = 2 and f (2) = (2)2 3 = 1. . Thanks. Step 1: Specify the set of options. Yes, econometrics is helpful as it lets users read the data or information obtained by assessing the particular pattern or trend indicated by a dataset.

Here are the steps that econometricians take to carry out an empirical study. Does the econometric model support this hypothesis. However, what usually ends up happening in life and in economics is that one item, either efficiency or equity, is chosen above the other. The third step is to estimate the unknown variables of the model using economic data at disposal. It confirms whether the primary hypothesis results derived were correct.

In modern econometrics, many statistical tools have come to the limelight, but simple linear regression is still the most routinely used starting point for an analysis. Its importance stems from the fact that, in large samples, many testing problems . At this stage, econometricians would define variables found in the economic model and the relationship between different variables. Rather than relying on complex theoretical discussions and complicated mathematics, this book explains econometrics from a practical point of view by walking the student through real-life examples, step by step.
